different from than - WordReference.com Dictionary of English
There is little difference in sense between different from, different to, and different than, and all have been used by respected writers. Different from is traditionally held to be the correct collocation, and is by far the commonest in written evidence; different than, which is often criticized, is largely restricted to North America.
Different from is the most common structure in both British English and North American English. Different to is also used in British English: Paul’s very different from/to his brother. ◇ This visit is very different from/to last time.
In North American English people also say different than: Your trains are different than ours. ◇ You look different than before.
Before a clause you can also use different from (and different than in North American English): She looked different from what I’d expected. ◇ She looked different than (what) I’d expected.
